PLOW.

SPECIFICATION forming part of Letters Patent No. 3300, 167, dated June17, 188 2.

A pplicntion filed March 22, 1884.

To all whom it may concern Be it known that I, DANIEL E. FISH, a citizenof the United States, residing at Vorthington, in the county of Noblesand State of Minnesota, have invented certain new and usefulImprovements in Flows; and I do hereby declare that the following is afull, clear, and exact description of the same, reference being had tothe annexed drawings, making a part of this specification, and to theletters and figures of reference marked thereon.

My invention relates to plows, and has for its object to provide meanswhereby the beam and meld-hoard may be adj nsted relatively, so as tothrow the plow-point low or high, and also to set the mold-board to takemore or less land, as desired. I accomplish these results by the devicesshown in accompanying drawings, in which Figure 1. is a perspective viewof the under side of aplow. Fig. 2 is a detail view of. the partsconnecting the foot of the standard and the landside, and Fig. 3 is adetail view of the parts connecting the mold-board and the upper end ofthe standard, all of which will be described.

The nioldboard A and the landside B are of ordinary construction, exceptthat the latter is provided about midway its ends with three transverseholes, for the passage of the bolts and pivot-stud which secure theserrated landsid'e-block in place. This landside-block O is provided onits inner face with a centrally-arranged stnd, D, fitted to be passedinto the central one of the holes in the landside before described.Holes :1 d are formed through the block near its ends, to permit thepassage of the retaining-bolts. These holes are elongated vcrtically,toadmit o't'aslight rocking motion of the block as the standard is ad justcd. The inner face of the landside-block is tapered from. end to end,as most clearly shown in Fig. land is provided with a series oftransverse serrations. The standard E is preferably bent from the rearend of beam F, and has its foot 6 adapted to engage the landside-block.This footpiece is provided with serrations corresponding to those in thelandside-block, and also with bo1tholes ti, which are elongated topermitthe ad- (No model.)

justinent of said foot along said block, in the nianner presentlydescribed. Bolts H H are passed through the openings in the landside,the block 0, and the standardi'oot, and have nuts h h turned against thefoot 0 and clamping said part, the block, and the landside together.

By the before-described construction it will be seen the landside isadjustable forward or back on the foot of the standard, and may besecured at any point desired. This adjustment, when the standard andmold-board are pivoted together at their upper ends, effects thelowering or elevating of the point of the plow, and causes same to rundeeper or shallower, according to the team or the class of work beingdone. Now, it will be seen that by removing the retaining-bolts H andreversing or revolving the landsi'debloclr half-way round on its pivotor stud the taper runs in an opposite direction from before. By thisconstruction I am enabled to throw the point of the plow to and from theland, so as to cut a wider or narrower furrow, as desired.

I prefer to connect the upper end of the standard and the mold-board bythe block I and the double-winged coupling-plate J. The

standard-block I has a bolt-hole, and is pro-- vided with a flange, i,turned from one end over one edge of the standard. This flange preventsany rotary movement of the plate on its retaining -bolt. The block I istapered from end to end, and has its inner face serrated similar to thelandsideblock before described.

The coupling 3' has the wings K Ill, one of which, R, is bolted to themold-board, and the other, L, provided with a bolt-hole, and is serratedon its inner face and operates in connection withthe stand ard-bloch, aswill be readily understood. This construction permits the adjustmentsaccomplished by the landside-block and the standard-foot, and provides afirm, strong connection, which, by loosening the retaining-bolt, willserve as a pivot. The handles M are secured to the standard near thelower end thereof, and are braced by a rod, in,

connecting the upper end of the standard and one of the handles. A bar,N, interposed between the landside and mold-board, serves to strengthenthe parts. The devices for adj usting the standard and mold-board enablethe adjustment thereof in such manner as to preserve the center draft.

It is manifest that a greater adjustment of the mold-board to or fromthe land could be accomplished by interposing suitable blocks betweenthedandside-block and the foot of the standard.

Having thus described my invention, what I claim, and desire to secureby Letters Patent,

winged coupling-plate having one Wing secured to the mold-board, and itsother wing serrated and engaging the standard-block and theretaining-bolt, substantially as set forth.

3. The combination, substantially as set forth, of the mold-board, thelandside, the tapered landside-block having a pivot-stud and serrated onits inner face, the standard having a foot provided with elongatedbolt-holes and serrated on its inner face, the retaining-bolts,

the standard-b1ock secured to the upper end of the standard and serratedon its inner face, and the double-winged coupling-plate having one wingsecured to the mold-board, and its other wing serrated and bolted to thestandard-block, as and for the purposes specified.

In testimony that I claim the above I have hereunto subscribed my namein the presence of two witnesses.
